Title: Discharge lamp lighting device
Inventor: NAGASE HARUO
IPC: H05B41/24
Filed: 1988-02-24
Abstract: PURPOSE:To facilitate effective supply of both high frequency power and DC power without instability in arc, in a lighting device for supplying alternately the high frequency power and DC power by setting the frequencies of both high frequency power and DC power at respective desired values. CONSTITUTION:A high voltage discharge lamp 1a is supplied alternately with a high frequency power having a frequency of fPH via a high frequency generation circuit 2, and a DC power interrupted at a frequency of fDC. The high frequency generation circuit 2 is connected to the primary coil L31 of a transformer Tf, while the secondary coil L32 of the transformer Tf, a capacitor C1 and a discharge lamp 1a form a closed circuit. A switching transistor Q1 for the DC power, a capacitor C1 and an inductance element L1 are connected together in series. By making frequency fHP higher than frequency fDC, and fDC higher than the resonance frequency fLC between the capacitor C1 and the inductance element L1, generation of arc instability due to the high frequency component is eliminated, and the high frequency power and the DC power are effectively supplied.

Title: Temperature control device
Inventor: UENISHI AKIO
IPC: G05D23/24
Filed: 1978-04-10
Abstract: PURPOSE: To remove transient feedback of a temperature control device by increasing an applied voltage when a heat sensitive thyristor is to be conducted so that the thyristor easily becomes ON to cause it to positively feed back.  
     CONSTITUTION: Since a triode AC switch 3 is conducted when the temperature of an article to be heated is low due to energization of a heater 2, an anode voltage is low at approx. 1 volt, and a capacitor 22 is not almost charged. The OFF voltage to be applied to a heat sensitive thyristor 16 at this time is not affected by a feedback circuit 25 but determined by a constant voltage diode 19, resistors 24, 12 as designated by VA(ON). The temperature is raised to cause the breakover voltage of the heat sensitive thyristor to become less than the VA(ON) so as to cause the triode AC switch 3 to become OFF. Thus, a capacitor 22 is charged at the power peak value. This voltage is higher than the VA(ON) to allow the applied voltage to increase when the thyristor 16 is to be conducted so that the thyristor 16 may easily become ON.

Abstract: PROBLEM TO BE SOLVED: To enable setting of an element to be tested to a specified temperature quickly and with a higher accuracy by a method wherein an opening part is formed on an end face of a heat transfer part and the element is pressed onto the opening part to directly contact a liquid through the opening part and a seal member arranged at the opening part. SOLUTION: Before the injection of a liquid A into a liquid tank 1, a seal member 11 is arranged in the perimeter of an opening part 1 of a heat transfer part 1b to keep the liquid A from leaking into a vacuum tank 2 and then, an element 4 to be tested is fixed by a screw together with a socket 5. At this point, the member 11 is pressed with the rear of the element 4 when screwed down to make a sealing between an opening part 10 of the heat transfer part 1b and the element 4. Likewise, a window 6 is fixed together with a cover part of the vacuum part 2 and a vacuum pump is connected to a vacuum hole 2a to evacuate the inside of the vacuum tank 2. Under such a condition, when the liquid A is injected into the liquid tank 1, the liquid A directly contacts the rear of the element 4 thereby shortening the time until the element 4 reaches a test temperature.

IPC: D06F33/02
Filed: 1978-04-14
Abstract: PURPOSE: To enlarge a drum weight at a starting stage of dehydration and to suppress a resonnance at an initial stage of dehydration in the prevention of maldistribution of the washing, by starting a hehydrating rotation while washing water is still stored in adrum.  
     CONSTITUTION: Immediately after completing a cleansing process, a drum 7 can start to be rotated at a high speed without draining water stored in an outer bath. A cum switch 37 is changed over to a side of a contact (a) for high speed, a motor 17 starts to run. A cum switch 37 is closed on a side of the contact (a), and opens a drainage electromagnetic valve 20. A dehydrating process starts only when a water level reaches a given level and a level detecting circuit turns on. A switching circuit 28 turns on when a water level arrives at a given level and contacts an electrode of a water level sensor unit 24, and becomes a self-holding circuit which keeps being closed even if the water elvel lowers due to relays S1 and S2 which close. A dehydrating circuit can thus be maintained until the circuit is disconnected after completion of dehydration.
